Studies on the Corrosion Inhibitor (Ⅱ)

Inhibitor에 관한 연구 (Ⅱ)
Kae Soo Lee

This investigation was made to evaluate the corrosion inhibiting effects of urotropine for mild steel in HCl. 1) Formaldehyde produced by the decomposition of urotropine also showed positive inhibiting effects. 2) In the presence of the ions, such as Cu+, Cu++, Fe+++, SO3=, SO4=, NO2-, NO3-, Cr2O7=, the inhibiting capacity of the urotropine was decreased. Alkali and alkaline-earth metal ions had no effects but the halogen ions improved it. 3) From measurements of polarization curves, it was assumed that the anode reaction was more retarded by the urotropine and the halogen.
